I only planned on building one, but the futzed first one caused me to build a second. If this doesn't work though, I might look into renting a jig from somebody.

What does the step jig do that the normal jig doesn't? I take it there is supposed to be a step in the upper rails but I have no idea what this means...

thats how i started-only intended to build just one!(there kinda like potatochips)i couldntget th rails right myself with the grasshopper
so i figured if i get more kits thatll justify getting the ak builder jig:brows:
when the ak design switched from the milled reciever of old to the newly stamped reciever the stepped rail was put in place so that they can use the
same bolt and carrier -if you look at some of the reciever stubs from demills
you might be able to see it-it looks like a groove in the rail from up top
i have my jig on loan right now for a while otherwise i would loan it to you
i wont be getting it back untill after christmas-when your post count gets up to speed or even before post in the classifides that you are lookin to rent one-im sure theres others willing to help out
yea sj in semi its probably not neccesary but it would probably function a lot smoother-ill have to put that on my christmas whish list-and make the appropriate notch on the die for where it fits(i allso should order more dremel bits!!!! ):loopeye:

Looks just like the one I made! I use long bolts to pull the flat through the jig resulting in near perfect bends. I also use a lot of grease on the flat to insure a smooth bend and easy pull.

Great thread! Does anyone have more info on the top rail and the best way to bend with limited tool at home.

I am definitely going to try this. I like the idea of an under folder, but in ‘Komifornia’ it’s got to be a minimum of 30” folded. How would I add 7” to the length of an under folder? Are there REALLY longer muzzle brakes/flash hiders?

Sorry for all the questions.

hk404me - bending the top rail can be done different ways. There are some threads with discussion about here at gunco. As for a long muzzle brake, maybe you could get one custom made to the length that you want. :)
I've seen some long muzzle brakes, but aren't positive to how long they were.

Alright. No more being leery...

I bit the bullet and spent the $10 at Lowes. Assembled. Measured 4x.

Although there was a little bowing on the 1" angle iron and the 3/8ths bar stock did bow a little too, the method worked perfectly the first time.

I do see how important getting the bar bolts tight to hold the flat steady, grease, and a press. Piece of cake.

Jeepers. Step up the angle to 1.5 or 2 and the bar stock to 1/4 and forget the $100+ jigs. Only solution they have over this is the dimensions for top rail built in. Poor man's solution is to buy flats with the top rails prebent.

This Jig with Ak-Builder's (Curtis's) new flats with stepped top rails already bent = one super easy receiver.

Lock N' Load

Hello all,
I am new here 1st post and I know I am throwing this on the end of an old but still Germain thread. A buddy and I have decided to start with flat builds and have never been down this road before. I just bought my 1st HF spot welder and powder coating system. Is the "grasshopper" still considered a viable solution or has it been supplanted by still simpler/cheaper idea?
